The great American total solar eclipse of 2017 is upon us.
On Monday, the moon will slip in front of the sun and cast a dark shadow that will travel across the contiguous United States. A partial solar eclipse will be visible around the entire country, but totality – when the moon fully blocks the sun and produces eerie-looking effects – can be seen only within a 60- to 70-mile-wide sliver.
The path of totality will touch 14 states, but hotels in those regions began selling out a year ago. If you’re not planning to travel and brave the traffic, though, there will be plenty of ways to watch a livestreamed video of the eclipse.
Below, Business Insider has compiled a collection of what should be the best feeds. As new ones go live, we’ll embed or link to them – so bookmark this page for later.
NASA is pulling out all of the stops with two live feeds of the solar eclipse, via NASA TV and NASA Edge, across multiple popular streaming-video services. We recommend watching those.
NASA’s first stream goes on air at 8:45 a.m. PT/11:45 a.m. ET, about an hour before the darkest shadow of the moon, called the umbra, first touches Oregon.
From there, the umbra will zoom southeast at between 1,440 and 2,370 mph, ending its American journey 93 minutes later in South Carolina. This map shows where and when the umbra – and totality – will arrive across the US:
When a feed will broadcast totality depends on where its cameras are. The longest totality will last at any location is less than three minutes, but some feeds will have dozens of cameras sprinkled across the country.
Note: You may need to disable Flash and ad blockers for the feeds to work. We’ve also included links directly to the streaming sites in case you’re having trouble watching.
1. NASA TV
On solar-eclipse day, the space agency’s main feed is going to be epic.
NASA TV has mapped out live video coverage for its “Eclipse Across America” segment from 12 locations on the ground, jets in the sky, telescopes, and dozens of high-altitude balloons. (Yes, we said “epic” for a reason.) These feeds should run from about noon to 4 p.m. ET.
2. NASA Edge
NASA Edge is the space agency’s edgier video production and is typically unscripted. Its feed will be a “megacast” of the solar eclipse from Saluki Stadium in Carbondale, Illinois, and will run from 11:45 a.m. to 4 p.m. ET.
In addition to NASA Edge’s main live feed, you can watch direct feeds of the eclipse from the H-Alpha Telescope, the Ca-K Telescope, and the White Light Telescope. It’ll also have a channel to show off freshly processed photos of the event.
This company has partnerships with observatories all over the world, allowing it to stream almost any astronomical event. We like Slooh because it fills its broadcasts with commentary from a rotating cast of experts who speak conversationally.
On eclipse day, it’ll base its broadcast out of Stanley, Idaho. The feed should go live at noon ET, but you may need to register to watch.
Stream is a newer, interactive video-feed service that we don’t plan to embed here, but you can access it for free at eclipse.stream.live on Monday.
Stream has partnered with NASA to string together an interactive feed that will feature footage from 52 high-altitude balloons launched from schools, universities, astronomy clubs, and elsewhere in the path of totality. The balloons will fly 100,000 feet in the air.
“The viewer will be able to pick which balloon they want to watch via the interactive map on the site,” Will Jamieson, Stream’s CEO, told Business Insider in an email.
Stream’s balloon cameras “will be aiming horizontal” to capture “both the Earth as well as space,” Jamieson said.
This means there’s a very good chance the feeds will show the oval-shaped umbra speeding across the ground as it races east.
